They are some of the harshest environments on earth, but deserts are still teeming with life and desert animals that have adapted to extreme conditions. To conserve water, a lot of animals don't urinate and most don't even drink water - they extract moisture from the plants and creatures they eat. What animals live in the desert? There are all kinds of desert creatures that are super cool, even if their habitats are hot as blazes.

The sidewinder rattlesnake beats the heat by moving in a way so that only a small part of its body is touching the scorching sand at any given time. The fennec fox has large ears to dissipate body heat. Other animals decide to hide during the day and sleep, coming out to feed at night, when it's cooler. There is even a type of beetle that pulls precious early morning moisture from the sand and gulps a big drop for a day's work.

It's hot out there, but these animals are so cool for finding unique ways to live in the desert? Which on this desert animals list is the coolest? The fearsome Gila monster? The adorable meerkat? The I-can't-believe-it's-real camel spider? Vote up your favorite desert denizens and learn even more about the desert biome.
